POWDER-Box.

SPECIFICATION forming part vof Letters Patent No. 621,686, dated March 21, 1899.

Application filed J' anuary 10, 1899. Serial No. 71,'705. (No model.)

To all whom it may concern:

Be it known that I, EDWARD l-l. LYON, a citizen of the United States, residing at Englewood, county of Bergen, and State of New Jersey, have invented certain new anduseful Improvements in Powder-Boxes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to powder-boxes of that class used for tooth-powder and similar `material in which the powder is discharged from the box as desired through one or more side openings in a discharge-tube, which tube is drawn out from the box for discharging the powder and pushed in to close the boxas, for instance, in the tooth-powder box shown and described in United States Letters Patent No. 577,767, granted to me February 23, 1897.

In powder-boxes in which the dischargetube has a cap formed separate from and forced onto the tube and forming a handle for use in withdrawing the tube, as shown and described in said Letters Patent, it is found in practice that the forcing together of the tube and cap under the heavy pressure required for securing the cap to the tube is liable to result in the compression of the end of the tube as the depressed ring of the cap passes over it unless quite heavy metal be used in the discharge-tube. The result of this compression of the end of the tube is f that the desired strong hold of the cap on the tube by the depressed ring is not secured, so that thel cap is liable to be pulled off the discharge-tube in withdrawing the latter against the considerable resistance to movement of the tube in the cover, which is necessary to secure a powder-tight connection, and this sudden release of the cap from the tube in withdrawing the latter results in a sudden jerk of the powder-box, which is liable to throw the powder from the discharge-opening and scatter it over the person of the user. Moreover, in powder-boxes of the special construction shown and described in said Letters Patent No. 577,767, in which the depressed ring not only holds the cap on the dischargetube, but also forms a gage-ring to secure the proper position of a collar carried by the cap and fitting over a neck on the box-cover, a

further result of this compression of the end of the discharge-tube is that the depressed ring does not vproperly perform its function as-a gage-ring, so as tosecure the proper relation between the collar and discharge-tube for coaction of the collar with the neck on the box-cover, and the t of the collar on the neck is either too loose to make a powdertight closure or too close to work properly.

The present invention provides an improved construction of such powder-boxes by which very light metal may be used in the discharge-tta'dat the same time all danger of pulling the cap off the discharge-tube is avoided and the proper action of all the parts secured, including the gage action of the depressed ring in connection with the collar and neck when these devices are used. l am thus enabled alsowith a light-metal discharge-tube to make the cap and its collar more accurately to the neck measurement, so as to secure a ybetter t and closure between the collar and neck, as no allowance need be made for possible variation in action of the gage-ring, and the invention also permits a tighter tit of the discharge-tube in the neck of the cover and a better closure against the escape of powder about the neck on account of the stronger pull that may safely be exerted upon the cap in withdrawing the discharge-tube. I secure these results by forming in the upper end of the discharge-tube an outward projection or projections above the depressed ring, so that the pull of the cap upon the discharge-tube in withdrawing the latter is sustained by the positive engagement of these projections with the ring. With this construction it is obvious that the pressure by which the cap and discharge-tube are forced together may be much lighter than where the pressure is depended upon to secure the parts together solely by surface friction and that a positive hold of the cap upon the discharge-tube and the proper action of the gage-ring may be secured although very light metal be used in the discharge-tube and cap.

For a full understanding of the invention a detailed description of a construction embodying all the features of the same in its preferred form as applied to the powder-box of the Letters Patent above referred to will now be given in connection with the accompany- IOO ing drawings, forming a part of this specification, and the features forming the invention will then be specifically pointed out in 'the claims.

In the drawings, Figure l is a longitudinal section of the box closed. Fig. 2 is a similar view showing the box open for theV discharge of powder. Fig. 3 is an enlarged detail View of the upper end of the discharge-tubel and cap. Fig. 4 is a section on the line 4 of Fig. 3. Fig. 5 is a View similar to Fig. 8, showing a slightly-modified form of projection on A the tube.

Referring to the drawings, the box shown is in general construction and operation the same as thebox shown in the Letters Patent above referred to, so that a brief description herein will suffice.

A is the box, preferably cylindrical, as shown, but which may be of any suitable form, and B is the cover, permanently secured thereto, so as to form a powder-tight joint and prevent the cover being pulled off, preferably by the rib-and-groove connection l. The coverB has the neck a, within which moves the side discharge-tube C, having the side discharge-opening s and preferably slotted at S, as shown, so as to form a springinnei` end and secure the desired tight fit and powder-tight closure between the tube and neck, and preferably having the flange or shoulder 9 at its extreme inner end, forming a positive stop for the tube in its withdrawal. Upon the outer end of the discharge-tube C is the cap D, which forms the handle for operating the tube and is provided with the expanded handle-knurl 5 and the depressed ring 6, which holds the cap upon the tube and forms a gage-ring for the collar b, which coacts with the neck a in securing a powder- .tight closure of the box when the tube is pushed in.

All the parts above described are shown as ofthe same form and construction as in the powder-box of the Letters Patent above referred to,except that the cap D andpdischargetube C are secured together in accordance with the present invention instead of being simply forced together under heavy pressure, as described in said Letters Patent. As shown in Figs. l to 4, portions of the discharge-tube C near its outer end are forced outward into the space formed in the expanded knurl 5 above the depressed ring G, so that the outward projections thus formed on the discharge-tube take over the ring 6 and sustain the pull on the cap by their engagement with this ring. Three of these projections a: are shown arranged at equal distances around the upper end of the dischargetube; but it will be understood that this number may be varied or that a continuous projection or expanded ring az may be used, as shown in Fig. 5. The series of projections a or continuous projection are preferably formed by forcing out portions of the tube, which may con veniently be done by inserting a small expanding-tool into the dischargetube from its open end, and this is preferably done after the cap has been forced onto the tube. It will be understood, however, that the projections on the tube may be formed in any other suitable manner, so as to secure the result desired, and that the invention is not limited to this or any particular order of steps in making the projections and putting the cap onto the tube.

Vhat is claimed isl. A powder-box having a side dischargetube moving longitudinally in an opening in the box to open and close the box, a cap on said tube formed separately from the tube and forming the handle for operating the tube, said cap having a depressed ringextending about the discharge-tube, and a projection on the discharge-tube extending outwardly from the tube above the depressed ring on the cap and engaged by said ring to sustain the pull on the cap in withdrawing the discharge-tube, substantially as described.

2. A powder-box having a neck, a side discharge-tube sliding in said neck to open and close the box, a cap on said tube formed separately from the tube and carrying a collar fitting over the neck when the tube is pushed in to close the box, said cap forming the han- `dle for operating the discharge-tube and having an expanded portion and a depressed ring extending about the discharge-tube below said expanded portion and forming a gagering for the collar, and a projection on the discharge-tube extending outwardly into the expanded portion of the cap and engaged by the gage-ring to sustain the pull on the cap in withdrawing the discharge-tube, substantially as described.

3. The combination with the powder-box discharge-tube C and cap D formed in a single piece and having the expanded handleknurl 5, gage-ring 6, and collar-b, of a projection on the discharge-tubev extending outwardly into the knurl 5 and coacting with gage-ring 6 to hold the cap on the tube, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
